Characteristic
1. Coefficient of Friction:
PTFE, known for its low friction, boasts a coefficient as low as 0.05, minimizing resistance and ensuring smooth operation in dynamic sealing applications.
2. Temperature Resistance:
PTFE excels in temperature resistance, withstanding a broad range from -200°C to 260°C. This property makes it suitable for applications in extreme thermal environments.
3. Chemical Inertness:
With exceptional chemical inertness, PTFE remains unaffected by various chemicals, acids, and bases, ensuring stability and reliability in diverse chemical environments.
4. Dielectric Strength:
PTFE possesses high dielectric strength, making it an excellent insulator. This property is crucial in electrical applications where insulation integrity is paramount.
5. Surface Tension:
The low surface tension of PTFE, quantified at approximately 18 dyn/cm, contributes to its non-stick properties, preventing adhesion of foreign substances and enhancing cleanliness.
6. Water Absorption:
PTFE exhibits minimal water absorption, with a water absorption rate lower than 0.01%. This property ensures dimensional stability in varying humidity conditions.
7. Tensile Strength:
While PTFE has a lower tensile strength compared to some metals, its tensile strength of around 20 MPa is sufficient for sealing applications, providing structural integrity.
Advantages:
- Chemical Resistance:
PTFE's resistance to chemicals enhances its applicability in corrosive environments.
- Low Friction:
The low coefficient of friction reduces wear and tear, extending the lifespan of sealing components.
- Wide Temperature Range:
PTFE's ability to endure extreme temperatures makes it suitable for diverse industrial conditions.
Disadvantages:
- Cold Flow:
PTFE may exhibit cold flow under prolonged stress, causing deformation over time.
- Limited Load-Bearing Capacity:
Compared to some metals, PTFE has a lower load-bearing capacity.
